    摘要: A system includes a plurality of collector devices that are disposed to collect statistical information on packets that are sent between nodes on a network. The system also includes a stackable aggregator that receives network data from the plurality of collector devices, and which produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node. The stackable aggregator includes a manager blade, a database blade, and two or more, analyzer blades.

    摘要: Techniques for tracking dynamically negotiated port connections in a network include collecting statistical information on packets that are sent between nodes on a network, inspecting packets of control connections to detect payload fragments that denote ephemeral port negotiation and producing a mapping from a ephemeral connection flow_id to a control connection flow_id. The techniques also include checking the flow_id to see whether a flow record maps to a control connection.

    摘要: A plurality of flow collector devices is disposed to collect flow information on a network. Duplicate flow records received from the flow collectors are eliminated by determining whether a pair of flow records has the same, source and destination flow identifiers and were received within a predefined time-period. Non-duplicated flow records received from the plurality of flow collector devices are stored and used to produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node from non-duplicated flow records. The connection table stores statistical information of packets on the network based on a time-slice basis.

    摘要: A system for detecting network intrusions and other conditions in a network is described. The system includes a plurality of collector devices that are disposed to collect data and statistical information on packets that are sent between nodes on a network. An aggregator device is disposed to receive data and statistical information from the plurality of collector devices. The aggregator device produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node. The aggregator runs processes that determine network events from aggregating of anomalies into network events.
